Hello @scbgt, let me give you a warm welcome to the Fitbit Community. If you are referring to the FitStar app, note that each integration is independently and it wont matter what type of tracker you have, since all the information from FitStar or other third party app will sync directly to your Fitbit account.
For more details you can review the following post: What does the integration between Fitbit and Fitstar do?.
Hope this information helps. See you around.
